Because 42 doesn't go into 63, you have to go larger. Start by multiplying 63 by 2.
63*2=126
42 goes into 126 3 times even, so the LCM of 42 and 63 is 126 :)
Answer:
Y=X/3+3
Step-by-step explanation:
M= Y2-Y1/X2-X1
= 5-6/6-9
= -1/-3
= 1/3
sub x=6, y=5, M=1/3 into Y=MX+C
5=6/3+C
5=2+C
5-2= 2+C-2
3=C
Answer:
x =21
Step-by-step explanation:
PQR is 90°
so x +2x +27 = 90
3x + 27 = 90
3x = 90-27
3x = 63
x = 63 /3
21
